In process of installing a new bellows from Japan on my V8 Deardorff. I have tightened the screws mounting the front frame to the front standard of my Deardorff but am still seeing light between the bellows frame and standard. Should a good bellows snug right up tight and I am dealing with an inferior product?? Did not notice any sealant when I removed the original bellows from the front standard, only on the rear.
